SPECIFICATION forming part of-Letters Patent No. 568,709, dated September 29,

- Appiicaion flied March 24, 1896.

To all whom t may concern.

Be it known that I, GEORGE DANIEL SPIEL- MAN, a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Ink- Wells; and I do hereby declarethe following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in ink-wells and other like articles, vand is designed more particularly as an improvement, as to details of construction, on the'construction disclosed in my Patent 'No 548,728, granted to me October 29, 1895; and it consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view of 'my improved well, partly in plan and partly in section. Fig. 2 is a view in section of the same, showing the dip-cup in its upper or normal position. Fig. 3 is a similar view showing the dip-cup depressed for illing. Fig. 4 is a view of the dip-cup detached. Fig. 4a is a modified form of dip-cup; and Figs. 5, 6, 7, S, 9,10, and 11 are views of modiications.

A represents the body of the ink-well or other receptacle, made in a single piece of metal, glass,or other suitable material and provided with a reservoir, which latter is divided into three sections l, 2, and 3 of different diameters internally, the upper section being the largest, the middle or intermediate section slightly smaller than the upper section, and the lower section less in diameter than the intermediate section, the shoulders or ledges connecting the several sections being inclined downwardly, .thus preventing ink or other material contained in the well or bottle from settling thereon.

The mouth of the well is preferably as Wide as the diameter of the upper section of the reservoir, and is surrounded by the externally-screW-threaded flange 4.

Located within the reservoir is the dip-cup 5, normally supported in an elevated position by the coiled spring 6,'the lower end of which serial No, 584,634. No mode-I.)

latter rests on the ledge 7 separating the sections 2 and 3 of the reservoirl The dipcup 5 is provided eXteriorly with a flange 8, whichrests on the upper end of the spring, and is preferably provided with a smooth upper edge, as shown in Fig."4, but can, if desired, be provided with prongs, as shown in Fig. 4f. It is also provided centrally with a depression 9, forming an exterior projection 10, which latter is designed, when the dip-cup is depressed for filling, to enter the smallest section 3 of the reservoir, the projecting yportion being somewhat less than the depth of the section 3, so that when the dip-cup is seated in its lowermost position it rests on the ledge 7, with the lower face of the projection somewhat above the extreme bottom of the reservoir. By this construction the sediment on the bottom is not disturbed and stirred up every time the dip-cup is depressed for reiilling. The Inouth of the depression is made flaring, so that the ink readily gravitates into the depression therein, and when the dip-cup is up in its normal position this mouth rests well up to the lower end of the funnel depending from the top of the well. ,This top 12, in Figs. l, 2, and 3, is provided at its periphery with a depending iiange 13, screwthreaded internally for engagement with the screw-threaded flan ge 4 of the body of the well, a rubber gasket 14 being interposed between the top 12 and upper face ofthe flange for sealing the joint.

The top is provided centrally with a funnel-shaped opening 15, the lower open end of which is practically of the same diameter as the dialneter ofthe depression 9 in the dipcup 5. The lower end of this funnel rests in close proximity to the bottom of the dip-cup,

just sufficient space being left for the 'passage of the ink intothe depressed portion" of the bottom of the cup. By this arrangement an ample supply of ink is'always immedi` ately below the funnel, and all dangerof-injury to the nibsbf the pen by contact with 9 5 the bottom of the cup is avoided. The wide flaring mouth of the funnel 15 is surrounded by a rib 16, which forms a seat for the removable cap 17 which forms a closure for the well when not in use. Vith this device, as

ICO

in the patented device before referred to, the ink is poured into the body A in the usual manner and the top is then screwed or otherwise secured in place. By now depressing the dip-cup by a rod or any other suitable device the dip-cup is submerged and `filled, and is then permitted, by relieving the pres* sure thereon, to assume its normal position. As the dip-cup rises the funnel enters the same, and as the atmospheric pressure prevents the ink from rising in the funnel a portion of the ink in the cup is displaced and forced over the top of the cup back into the body. A liquid seal is thus formed between the funnel and dip-cup, which prevents the entrance of air into the body of the well and thus prevents evapora-tion of the ink therein. The ink taken from the depression in the bottom of the cup is replaced from the ink in the cup around the funnel, and hence it will be seen that only the very small quantity of ink immediately below the funnel is exposed to the air.

In the construction shown in Fig. 5 I have shown the body of the well of uniform thickness throughout its bottom, and provided with a` metal block 20 to fill out the sides surrounding the lowest section 3 of the well. In Fig. (l, I have shown a hollow block 2l for ac eomplishing the same result.

In Fig. 7 I have shown the funnel or top secured at its upper edge to a metal flange and provided with a lip adapted to take under the lugs on the top ilange et. The lip in this instance should be provided with slots for the entrance of the lugs, and the lip might be wedge-shaped, so as to securely clamp the funnel-top in place.

In Fig. S I have provided the funnel-shaped top with a depending flange 22, having a semicircular-shaped groove therein, adapted to aline with a similarly-shaped groove in the inner face of the wall of the well. The two semicircular grooves form a seat for a cylindrical-shaped rubber band, and when the latter is in place it is compressed sufficiently to lock the top in place and also form an air-seal.

In Fig. 9 I have formed the groove in the outer face of the body of the well and provided the top with a flange adapted to embrace the top of the well, a rubber band be ing employed, as in Fig. 8.

In Fig. 10 I have shown the well or bottle as flaring and provided at its upper edge with a series of lugs which are designed to be engaged by a series of nnderlapping lips integral with a peripheral flange 22, and in Fig. Il I have shown the funnel secured to the body of a ring 23, having upper and lower flanges, the upper flange resting on the top of the funnel-shaped top and the lower flange resting under a series of outwardly-projecting lugs integral with the body of the well, the lower flange having slots therein adapted to permit of the entrance of the lugs. lVith this construction I prefer to place a gasket between the top and upper edge of the body, as shown.

lVhile I prefer to make the body, funnel, and dip-cup of glass, I would have it understood that I do not restrict myself to such material, as I consider myself at liberty to use any other suitable material; neither do I confine myself to the details shown and dcscribed, but consider myself at liberty to make such changes as fairly fall within the spirit and scope of my invention.

IIaving fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. An ink-wel1 consisting of a main reservoir, a funnel extending into the main inkreservoir and a dip-cup or supplemental reservoir yieldingly supported with its upper edge above the lower end of the funnel and provided with a closed central depression im mediately below the lower end of the funnel, substantially as set forth.

2. An ink-well comprising a main inkres ervoir, a funnel extending downward into the latter, and a yieldingly supported supplemental reservoir or dip-cup having a closed depression centrally in its bottom, the said depression being in a line with the lower end of the funnel, the said supplemental reservoir or dip-cup normally resting with its upper edge in contact with the underside of the funnel-shaped top, substantially as set forth.

An `ink-reservoir comprising a main inkreservoir, a funnel depending into the latter and a yieldiugly-supported supplemental rcservoir having a closed centrally-located depression or well in its bottom, the said supplemental reservoir adapted to contain a supply of ink and normally hold a portion thereof above the lower end of the funnel, substantially as set forth.

4:. An ink-well, consisting of a body por tion provided with a reservoir composed of three sections of different diameters, a supplen'lental reservoir or dip-cup of two diameters, and a spring one end of which is in con.- tact with the larger section of the dip-cup, while the lower end rests in the middle scction of the main reservoir, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subserib ing witnesses.

GEORGE DANIEL SPIEIIMAN.
